The new legislation, which will be introduced by Rep. Carolyn Maloney (D-N.Y.) in the House, and Sen. Ed Markey (D-Mass.) in the Senate, would give the CDC $10 million a year "for the purpose of conducting or supporting research on firearms safety or gun violence prevention."

"In America, gun violence kills twice as many children as cancer, and yet political grandstanding has halted funding for public health research to understand this crisis," Maloney said in a statement.

A National Rifle Association spokeswoman called the push for new CDC funding "unethical."

"The abuse of taxpayer funds for anti-gun political propaganda under the guise of 'research' is unethical," spokeswoman Catherine Mortensen said in a statement to ProPublica. "That is why Congress should stand firm against President Obama's scheme to undermine a fundamental constitutional right."
